Science Weather Study Guide SOL 2.6
Terms to Know
 Earth – the planet we live on
 Wind – moving air
 Temperature – how hot or cold the air feels
 Precipitation- liquid or solid water falling form clouds; rain, snow, and ice (sleet and hail).
 Evaporation – liquid water changing into a gas because heat is added, usually from the sun
 Condensation – gas water changes into a liquid, usually within a cloud
 Drought – too little rain over a long period of time
 Flood – too much rain over a short period of time
 Storms – lots of precipitation with strong winds
Types of Storms: hurricanes, tornadoes, blizzards, and thunderstorms.
 The Earth’s weather changes continuously from day to day.
 Changes in the weather are characterized by daily differences in wind, temperature, and precipitation.
Precipitation occurs when water, previously evaporated, condenses out of the air and changes state from a gas to a liquid (rain) or to a solid (snow or sleet).

 Extremes in the weather, such as too little or too much precipitation, can result in droughts or floods.
 Storms have powerful winds, which may be accompanied by rain, snow, or other kinds of precipitation.
 Weather data is collected and recorded using instruments.
This information is very useful for predicting weather and determining weather patterns.
 Weather influences human activity.
Types of weather: sunny, cloudy, windy, rainy, or snowy
Measuring Weather: thermometer, rain gauge, and weather vane
